Bosch FMD-432 Red Fire Barrier Trigger Button Recessed Installation

It is the recessed installation version of the red button used for manual actuation of fire barriers. Its simple design, reminiscent of a light switch, does not stand out on the wall; its 81 x 81 x 20 mm body fits standard recessed boxes. It operates in environments between -20 °C and 40 °C. Thanks to standard box compatibility, there is no need to cut a special opening in the wall; it runs along the same line as the electrical infrastructure.
